Hello everyone hope you can help me!,

The problem i am having is with a external firewire 800 harddrive. My computer is a high spec, SONY Vaio K215M Laptop running windows XP service pack 2 with a GIG of ram. I dont have any firewire ports on the laptop so i use a 1394 3-port cardbus. Everything has been working perfectly, and i formatted the drive after i bought it and used it.

I turned it off one day and now, For no apparent reason now my computer wont pick up that the device is turned on, it just wont recognise it at all. The problem wasnt CAUSED by installing XP service pack 2, it has never been used with SP1. I havent installed any new drivers or any new programs the problem occured over night. Because my cardbus has 2 firewire 800 slots, when the hardrive first didnt work i used the second slot. The computer picked up the device, and this worked....for a day. And now neither of them work. The problem seems to be with plugging it in and out... I have checked for yellow exclamation marks to do with the drivers and there are none.

What can i do??

I tried MICROSOFT help and that was useless

Please help me!!

Thank you,

MichaelTry plugging your device in someone elses computer to see if it works, and try plugging another device you know works in your computer firewire port to see if that works.

This will FIND out wether it is the device or the computer that is the problemit works on another person computer no hope for me then i take it?  remove it from the device manager and re-plug it in...
